fixing tps?

[exzercist]

i logged my tps and it says full throttle is 94.7%. i know that it should be 100 or 99 so how do i adjust mine to be 100%. i figured i can have a friend look to see if the throttle body opens all the way or see if the cable pulls the throttle body to the stop point. but the tps is a sensor right so how can i adjust it.

loosen the two little screws and rotate it. also, I don't think you need it to read exactly 99-100%, as long as the value increases as the throttle opens.

what way do i rotate it to make the throttle higher? well some of the other guys on the site said that 94 isnt the same as 98 even though both are wot? im gonna try it

Moving the TPS so that it reads higher is the wrong way to go about addressing this problem.
The TPS should be set properly by adjusting the TPS to the point where the IPS opens as I've posted before.

Then you make sure that the throttle butterfly opens 100%. It's the mechanical issue that's important here not what your TPS reads. If your TB doesn't open all the way then you need to figure out if your cable is too loose, if your pedal is blocked from full travel, or if you have some other problem. If your butterfly is opening 100% then what your logger reads doesn't matter! The IPS setting is critical. Having your TPS voltage smoothly increase is critical but the actual voltages are not!

exzercist, how do you "know that it should be 100 or 99"?

other people that have logged have had there tps at 98 to 100 if theres are that high then mine should be to.

It's going to log what it logs. Some peoples sensor 5v aren't exactly 5v and the actual TPS resistance at WOT varies from TPS to TPS. Some OBD II loggers scale their results and some present raw values.

Like I posted, once the TPS is correctly adjusted by setting the IPS opening point the rest is a mechanical issue.
